Mitzi has a secret spot just like that - she's torn the underside of my California King box spring and crawls up into the box springs when she wants to hide. She knows I cannot reach her secret spot as it's smack-dab in the middle of the bed frame and I'm not tall enough to reach. It's her go-to spot when she knows I'm planning to take her to the vet.

My vet knows when she gets the call that I can't make the appointment because Ms. Mitzi has done it again.
